Using the concept of Boolean functions and combinatorics theory comprehensively, we investigate the construction on annihilators of Boolean functions and the algebraic immunity of symmetric Boolean functions in cryptography:Firstly, we introduce two methods of constructing the annihilators of Boolean functions, Construction I makes annihilators based on the minor term expression of Boolean function, meanwhile we get a way to judge whether a Boolean function has low degree annihilators by feature matrix. In Construction II, we use the subfunctions to construct annihilators, we also apply Construction II to LILI-128 and Toyocrypt, and the attacking complexity is reduced greatly. We study the algebraic immunitiy of (5,1,3,12) rotation symmetric staturated best functions and a type of constructed functions, then we prove that a new class of functions are invariants of algebraic attacks, and this property is generalized in the end.Secondly, we present a construction on symmetric annihilators of symmetric Boolean functions.

This was because of a miscalculation on our part which led us to believe the stat was worth less than it really was.

Methods the family members of 160 psychotic patients who had finished treatment in hospital were surveyed in demands for education such as health idea,content and way.results although the family members had a little of health information,they were short of health information guidance.some of them were lack of enthusiasm in the recovery of the patients so as to misdoubt that mental disease could be under control for long.but they needed much in the content of health education, and individual conversation was a way they liked to choose.telephone consultation was welcomed,as well.conclusion health education should be stressed in depth and extent,so are the content and the way.more helps need to be given to family members.

采用问卷方式对160例住院治疗结束后的精神病病人家属进行健康获得观念、教育内容、方式需求调查。结果家属有一定的健康信息储量，缺乏较深层次的健康知识指导；部分家属不相信精神病可以得到长期控制，对精神病人的康复训练缺乏热情；对健康教育内容需求较多，教育方式多选用个别交谈，咨询方式以电话咨询最受欢迎。结论家庭健康教育需加强知识的深度和广度，重视教育内容与形式的研究，加强家属的心理支持，需要得到全社会的共同关注。

Firstly, Hiscanner laser scan detector was adapted for data collection, and then obtain point cloud data which could be recorded on disc for permanent saving was obtianed; Furthermore, the new popular reverse engineering software Geomagic for some disposals of point cloud data was adopted in data condensing, data mending, data filtering, feature line picking up to obtain NURBS surfaces; and then the error between the reconstructed CAD model and the point cloud data was evaluated to guarantee the precision of surface reconstruction to keep the relics keep its original appearance. In the end, the NURBS surfaces are imported to 3D software Solidworks and entities of CAD are generated by surface sewing, mold loft and ablating and other instructions.
